I feed my boa 1 hopper mouse 3 days ago and it didn't even live a bump in her billy so should i feed another hopper. Also is a adult mouse the next size up from a hopper. Because id like to switch to a bigger mouse the next time i feed him. I want to feed him a rat fuzzy but i cant convince my dad to let me buy a rat fuzzy, i told them that they are better but he just tells me to steak with mice.
